Black Holes, New Theories and Revelations?

Recently more work has been put into
the researching of black holes, where scientists have looked into how
black holes work. Some recently believe that black holes have a
different way of working now. Two research papers have recently been
published, explain the circumstances and implications of
falling/sucked into a black hole.

Now we have covered that black holes
behave differently, relative to the person standing is different
positions in and around the black hole. Where one person looking from
the outside and sees another falling in, time will seem to slow down
infinitely and will literally freeze and stop moving completely, but
to the other person (falling into the hole) time flows normally. This
is due to Einstein's theory of general relativity. This event
happens on a certain part of the black hole, called the stretched
horizon (If I didn’t mention before), this is a hot part of the
black hole, which results the falling person, getting hotter or in
other words, thermalising and then eventually disappearing, releasing
back to the observer as a type of radiation called Hawkins
radiation(More on this later).

This new theory, is focused on the
traveller not the observer, everyone has established that what
happens to the observer is correct, at least to our current
understanding of physics. The theory re write or at least tries to re
write about how an event horizon effects the traveller. This theory
has determined that the event horizon is now a type of firewall,
where time and space ending instantly for the traveller. These new
papers, are trying to implement Quantum mechanics in the theory to
make the conclusion work. To explain why and how this works, we need
to establish that this theory only works for black holes that are
old, the idea of an old black hole is where the hole has actually
released or emitted more than half of the particle information that
it actually had when the black hole had been formed (Ideally from a
Neutron Star). This though is controversial, some say its to do with
page time or fast scrambling time. So it might not be EXACTLY
correct. This means it could be as old as the universe or even 1/10th
of a second old. As you can see there is a massive room for error
here and will eventually be establish in the future. Hopefully.

What is meant about how Quantum
Mechanics is used for the theory is because of this
information/radiation that is emitted and which is used to gauge how
the process works. Imagine particles of radiation being released and
sent into the cosmos, then following it is another few particles
behind it, ideally in the event or the edge of the stretched horizon,
they might be light years apart but that is irrelevant, really. These
particles or radiation are actually connected to one another, as in
they know about each other in time and space. This is what's called
“Quantum Entanglement”.

This is where two particles in the
universe no matter how far away they are. Somewhat connected across
the vastness of space.(This is also a form of Quantum Super
positioning), I might cover this in a future topic, to explain what
it is.

Now the crux of the matter is where the
event horizon, knowing it is between the stretch horizon. Believed
that the event horizon was nothing special other than knowing it is
the point of no return.

Imagine a particle after the stretched
horizon but before the event horizon and a particle on the other side
of the event horizon and between the stretch horizon, Seen below.

As you can see that, the two particles
that are between the Event Horizon. They are supposedly not connected
to each other, due to Quantum Entanglement (QE), meaning that the
event horizon is actually blocking the connection between both
particles, meaning they are not entangled. AS in, the particle that
is travelling deep into the cosmos, is not attached to the particle
that is inside the event horizon. They are completely independent
systems. So the conclusion is that the event horizon is actually
acting as a “firewall”, like the firewall on a computer or
router. That blocks virus and mal-ware attacks. Essentially a wall
that blocks the particles and ultimately one the traveller reaches
this event horizon, the person or thing will disappear instantly.
This is what's called burn up or others call it termination, to
convey the ultimate finality to anything that enters it.

Though we have made significant
progress in further our understanding, I would say we are just
starting to chisel of the top of the iceberg.

About Me

Since this is not a personal blog, I will disclose very little about myself. I enjoy science and wish to make this site a vessel for scientific knowledge. I will not post up personal information of any sorts about myself (Facebook, Address Book etc.). Enjoy the journey.
